Benefits of technology
The present invention provides an alternative color blending apparatus for a 3D printer that can accurately mix separate colors to create the desired output color for dots in the object. The apparatus automatically blends the colors, so the user does not have to intervene after the printing instruction is made. The invention allows for printing with a vast spectrum of colors using a single printing head, making it more accurate than what is present in the computer design model. The printing process is carefree for the user, with the machine automatically blending the colors and starting a new printing operation when the previous one is completed.
Problems solved by technology
However, traditional desktop color 3D printers have various drawbacks that impede users from obtaining a resulting object in the exact appearance as they would expect.
For example, due to limitations in the printers, there are often an insufficient number of colors exposed in the printed object.
However, this kind of color printing not only requires a complicated multiple printing head system demanding substantial cost and system complexity, but also the outcome color is depended on the material color.
Such printing technique would not be sufficient to provide the vast spectrum of colors that are widely used in the computer designs and can be shown by almost all modern display devices.

Embodiment Construction
[0068]In the claims which follow and in the preceding description of the invention, except where the context requires otherwise due to express language or necessary implication, the word “comprise” or variations such as “comprises” or “comprising” is used in an inclusive sense, i.e. to specify the presence of the stated features but not to preclude the presence or addition of further features in various embodiments of the invention.
[0069]As used herein and in the claims, “couple” or “connect” refers to electrical coupling or connection either directly or indirectly via one or more electrical means unless otherwise stated.
[0070]Referring now to FIGS. 1 and 3-5, the first embodiment of the present invention is a three-dimensional object printer 20 which is equipped with a color blending apparatus, so that a vast spectrum of colors may be outputted by the printer in a high color resolution. The printer 20 contains a casing 22 substantially in a cubic box shape, but with an open top. On...

Abstract
Apparatus for blending colors for a three-dimensional object printer, includes a mixing chamber, a heating device connected to the mixing chamber for heating up the mixing chamber, and a guiding device including a plurality of color ingredient inlets. Each color ingredient inlet is adapted to receive a color ingredient for a single color. The guiding device is coupled to the mixing chamber such that the color ingredients are adapted to pass through the guiding device to enter the mixing chamber. The guiding device is configured to guide the color ingredients passing through the guiding device such that a vortex of the color ingredients is formed in the mixing chamber and exit via a mixed ingredient outlet. Also shown are a method and a 3D object printer. Effective color blending is provided in a single printing head achieving high definition color output capability by a relatively simple printing head structure.
Description
FIELD OF INVENTION[0001]This invention relates to three-dimensional object printers, and in particular structures and working principles of printing heads in such printers.BACKGROUND OF INVENTION[0002]Three dimensional (3D) object printing is one of the hottest new technology areas nowadays, which provides a brand new way of fabricating three dimensional objects based on computer 3D modeling or 3D scanning to a real object. Applications for 3D printing are found for example in artistic design, architecture, engineering and construction (AEC), automobile, aeronautics and astronautics, dental and medical industries, education, geographic information systems, civil engineering, and so on. As the 3D printing technology evolves rapidly, color 3D printing is also now possible for printing a 3D object with different colors applied to different parts of the object.[0003]However, traditional desktop color 3D printers have various drawbacks that impede users from obtaining a resulting object ...
